  Stackpole has expanded its CSS series of current sense chip resistors to include a 0.33W rated 0603 size and a 0.5W rated 0805 size. Both offer resistance values of 5, 10, and 15mΩ in 1% tolerances and 50ppm TCR.

  Utilising high voltage power film to achieve high working voltages and high overload voltages, the ASR/ASRM series of anti-surge resistors has been released by Stackpole. The devices withstand repeated high voltage pulses of up to 10KV every 5 seconds with very little resistance shift.

  Stackpole Electronics announces the release of the RAVS series of convex termination anti-sulfur chip resistor arrays. The RAVS series utilises thick film technology with lower silver inner terminations to significantly reduce the susceptibility of the array to contamination by sulfur.

Stackpole Electronics announces its tolerance expansion for the RGC series. The thick film technology is now available in ±0.1% tolerances in chip sizes from 0603 through 2512. This development is a significant enhancement to the series that allows engineers to take advantage of precision tolerances while avoiding design challenges associated with thin film resistors, namely high moisture/humidity.

  Stackpole Electronics, has released the HCC8420 high current chassis mount shunt resistors. The HCC8420 is rated at 15W and has a resistance value of 0.1mΩ and can handle currents up to 350A. The TCR for this part is an impressive 100ppm/°C.

  A series of foil on ceramic current sense chip resistors that offers resistance values among the lowest in 0402 and 0603 chip sizes has been released by Stackpole Electronics. The CSRF series consists of the CSRF0402–HP and the CSRF0603.

Stackpole’s EWT Series of vitreous enamel coated tubular wirewounds are a good choice for high power load dump applications. The EWT Series is available in power ratings from 12 watts up to 1300 watts and the vitreous enamel coating withstands temperatures of up to 500C.

The RAF Series from Stackpole is a small size chip resistor array consisting of two or four isolated 0201 equivalent resistors in a single rectangular shaped chip with no scallops or holes. By removing the scallops that chip arrays usually have, the substrate becomes less complex and less expensive.

The ZOV Series of metal oxide varistors is a series of epoxy coated square varistors with sizes from 23mm to 60mm. These high energy varistors come in a single disc, double, triple and quadruple disc versions with pulse current capabilities of up to 80kA.

The RNCP series from Stackpole has no silver or other susceptible metals in the terminations to cause sulfur contamination. In addition, the thin film resistive element provides outstanding stability and higher power ratings compared to commodity thick film chip resistors.

Stackpole’s RC series is an axial leaded carbon composition technology available in 1/4W, 1/2W, and 1W power ratings. The RC’s dense carbon slug element handles high energy surges much better than metal film based surge resistors.

Stackpole announces the release of the CSRF0603 and CSRF0402 sizes to add to their broad current sense resistor product group. The CSRF0603 is available in resistance values from 5 to 10 milliohms in 1% tolerance and 75 ppm TCR.

Stackpole Electronics, Inc., through its strategic alliance with KEKO Varicon, announces the AVL Series of radial leaded automotive varistors that are designed to protect automotive level electrical systems from transient voltage events. The AVL Series is designed specifically to protect 12V, 24V, and 42V automotive electrical systems.

The BR series from Stackpole is a thru hole current sense resistor series offering power ratings up to 5 watts with low PCB temperatures. The BR series elevates the resistive element off of the board for maximum cooling into the ambient air and minimizing the amount of heat that must be dealt with at the board level.

The HMC series from Stackpole is a thick film based chip resistor series capable of high resistance values. This series utilizes special high resistance inks and volume production to achieve a chip resistor that is capable of extremely high resistance values without significant cost increase.

Stackpole Electronics announces the release of the SM8035 4 watt molded SMD wirewound resistor. The robust wirewound element is able to withstand much higher surge energy than other film surge resistors. The SM8035, in a 1 ohm value for example, has the energy handling capacity of 43.3 Joules.

The RAVN Series from Stackpole is a thin film based chip array designed for applications with tight tolerance or tight TCR requirements. The RAVN Series offers four resistive elements in a package measuring 1.6mm by 3.2mm with resistance values from 100 ohms up to 33K ohms in a 0.1% tolerance. This part can also achieve 10 ppm TCR for a limited resistance value range.

The RNCH is a high power version of Stackpole’s award winning RNCS series of anti-corrosive passivated nichrome thin film chip resistors. The RNCH offers the power rating of the RNCS0805 in the 0603 size and similar power upgrades for the 0805 and 1206 sizes.

The RHC2512 is a two-watt thick film chip resistor which utilizes special materials, design, and processing to achieve low heat rise compared to other high power chip resistors. The RHC2512 has a hot spot temperature of just under 120C at 2 watts where most 2512 size chip resistors may reach that temperature at only 1 watt of applied power.
