Power resistors sink the heat
Ohmite has produced what it reckons is the industry's first thin film power resistor in heatsinkable packaging.
Ohmite has produced what it reckons is 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 0.03ohm 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 4ohm to 10kohm and 10mohm to 10kohm, respectively.
The Ryton case is fixed to a black anodised aluminium heatsink.
Ohmite also provide a recommended mounting bracket kit.
