100W, 150W high - pulse absorption resistors.

Technical Features and Application Scenarios

• Technical Features:

• Suitable for installations without forced air cooling (fan can enhance effect).

• Primarily used in circuits that require absorbing large pulse energy in a short period, offering advantages such as inductance-free, high thermal capacity, high temperature resistance, small size, and stable performance.

• Ideal for random high-pulse energy discharge resistors, braking resistors for variable-frequency motors, etc.

• Application Scenarios:

• Circuits with high pulse energy absorption requirements.

• Environments with high demands for resistor performance stability and high temperature resistance.
