The AVY series is rated for up to 2,000A of current and 25J load dump energy.

It has been recently announced by Stackpole Electronics, that the 0805 and 2512 package sizes of its CSRF series current sense chip resistors are now qualified to AEC-Q200. The CSRF utilises a foil on ceramic carrier technology that is impervious to sulphur and offers low resistance values, good TCR, and the ability to achieve small sizes.

The CSR series of thick film current sense resistors from Stackpole Electronics is available in a wide range of sizes and resistance values. The CSR / CSRN is available in resistance values from 3mΩ to 1Ω, depending on size, and in tolerances down to 1%. Sizes range from 0402 (0.125W) to 2512 (2W), along with a 1225 with long-sided terminations that is rated at 3W.

The SM Series wirewound resistor offers a robust surface mount device capable of handling up to 4W in a single part. The SM8035 case size can handle over 50J of energy while the SM2615 size can withstand more than 5 times the energy of a comparable size pulse withstanding flat chip resistor. A single SM is an ideal solution for applications that demand high continuous power with low heat rise.

Stackpole Electronics has announced that its TR series now offers power ratings of 20 to 50W for the TO-220 packages and 100W for the TO-247 package. These non-inductive and RoHS-compliant packages are suited for use with power IC’s on heat sinks to help maintain the 25°C film temperature. The TR series is available with tolerances as tight as 0.5% and TCR as low as 50ppm.

The CSRF0402 foil on ceramic resistor from Stackpole offers industry-leading low resistance values with good TCR. Stackpole now offers a 3mΩ resistance value in tolerances as tight as ±1% and TCR of 200ppm. The CSRF0402 is also available in 5, 10 and 15mΩ resistance values, making it suitable for a wide variety of consumer and industrial portable electronics that require high efficiency current sensing and small size.

Designed for applications requiring good surge handling and fusibility to prevent significant heat generation or fire, the SP3A series has been announced by Stackpole Electronics. The axial leaded 4W wirewound resistors can survive hundreds of 3kV surges of less than 50µs without failing or significantly shifting resistance. They will also fuse quickly and without flame or significant heat when subjected to continuous overloads of 120VAC or...

The HVC series from Stackpole is a thick film surface mount chip resistor series designed for high voltage handling and high resistance value. In response to growing market demand for resistors with both high voltage handling and high precision, Stackpole has expanded the number of resistance values available from stock.

Stackpole Electronics's ASR Series of anti-surge metal film resistors are rated for high voltage applications. Working voltage for the ASR Series ranges from 1150 to 4000V with overload voltage from 1500 to 5000V. In addition, the ASR can handle high voltage capacitor discharges from 3KV for the smaller sizes up to 10KV for the larger.

Providing resistance values of 5-40mΩ, 1% tolerances and TCR as low as 75ppm, Stackpole has announced the 1.5W rated CSRF0612 series current sense chip resistors. The 0612 size designation denotes that the termination is on the long sides of the part as opposed to the short ends, as with the 1W rated 1206. This longer termination provides higher current handling and lower thermal resistance.

Stackpole's RNCP series chip resistors utilise high volume thin film technology to provide cost effective chip resistors that are 100% lead free and RoHS compliant without exemption. The RNCP's thin film technology doesn’t require the lead containing dielectric as do most commercial high volume thick film chip resistors.

  The HVC series from Stackpole is a thick film surface mount chip resistor series designed for high voltage handling and high resistance value. The working voltages for several chip sizes have now been improved: the 1206 size now is rated at 1500V, the 2010 is now 2000V and the 2512 is now 3000V.

Stackpole announces the release of the MLFA Series of AEC-Q200 qualified precision metal film melf resistors. AEC-Q200 has become an important passive component qualification standard for a variety of industries and end products and is no longer merely an automotive requirement.

Stackpole Electronics has announced that its CSRF series of SMD current sense resistors is now available in resistances down to 5mΩ in an 0402 chip size. This low resistance value, combined with the small package size, enables efficiency improvements in small portable electronic devices and potential downsizing of existing designs.

Stackpole has revealed that its HCS high current SMD shunt resistors are now available in a 0.2mΩ resistance value in chip sizes of 3920 and 5930. The HCS has an all metal welded construction with a raised resistance element which provides more efficient thermal conduction, allowing the HCS to handle higher currents with lower self-heating compared to comparable flat chips.

  Stackpole Electronics has announced that its CSSH2512 3W current sense chip has now been qualified to AEC-Q200. The CSSH2512 offers resistance values from 0.5 up to 10mΩ in tolerances as tight as 0.5% and TCR as low as 25ppm.

Stackpole's BR series is a radial leaded thru hole current sense resistor series offering power ratings up to 5W. The BR series elevates the resistive element off of the board for maximum cooling into the ambient air and minimising the amount of heat that must be dealt with at the board level.

Stackpole's RPC Series of anti-surge chip resistors is now AEC-Q200 qualified for 1% tolerances and wider. Along with providing top notch pulse handling, the AEC qualification provides additional assurance to designers that the RPC Series is able to pass the stringent electrical and environmental requirements set forth by the AEC standard.

The HCS series from Stackpole now includes an 0.2mΩ resistance value in the 3920 and 5930 chip sizes. This extremely low resistance value allows higher power current sensing with greater efficiency. In addition, the all-metal raised element means lower PCB temperatures due to increased convection under the part. The HCS typically runs 15 to 30°C cooler than comparable sized flat chips.

Resistant to the effects of both sulfur and moisture, a series of thin film precision chip resistors have been unveiled by Stackpole Electronics. While thin film nichrome resistors typically have difficulty withstanding high humidity environments under low power, Stackpole's proprietary materials and processing protects the nichrome element and performs as well under high humidity testing as much more expensive technologies such as tantalum nitri...
