Type R5000 Series
Characteristics - Electrical
Derating Curve Pulse Energy (Foil Element)
The R5000 by TE Connectivity is a high specification flat resistor module with flying
leads, designed for snubbing applications where size and weight are at a premium.
With a height of 13mm, an overall weight of 150g, and a rated power of 250W, this
resistor offers unbeatable performance in terms of power density. Advanced
construction methods and high performance materials give a rugged and resilient
device capable of high pulse energy absorption, low inductance, high
stability, and a low TCR. This device can be fused to offer circuit protection and is
available in a wide range of resistance values.
