Ohmite, TK/TN Series

Heatsinkable Thin Film Power Resistor from Ohmite

News Release from: Ohmite (Europe)

Ohmite has produced what it claims to be the industry's first thin film power resistor in heatsinkable packaging. The TK/TN Series also offers other major advantages over existing TO-220 products, namely, low resistance values down to 0.03 ohms for current sense applications and low cost.

The use of thin film technology enables Ohmite to offer customers enhanced performance advantages such as being extremely stable (low TCR), low noise (parasitic capacitance and resistance), excellent high frequency performance and
high accuracy (tight tolerances).

The 15 and 20W heatsink dependent devices have resistance ranges of 4ohms to 10Kohms and 10mohms to 10Kohms and respecitively. The Ryton case is fixed to a black anodized aluminium heatsink. Ohmite also provide a recommended mounting bracket kit. Fully RoHS compliant, thick film versions are also available.
