Description

5W Non-Inductive Cement Resistor — High Pulse & Surge Performance

This 5W cement-type resistor is designed for circuits that require stable operation under frequent pulses and surge loads. With a low-inductance internal structure and excellent thermal endurance, it maintains consistent performance in power electronics and industrial control environments.

Key Features of Non-inductive Resistor

  1. Non-Inductive Construction — Minimizes parasitic inductance for accurate performance in high-frequency and switching environments.

  2. High Pulse Tolerance — Cement body and robust internal structure withstand repeated surge and pulse loads.

  3. Excellent Thermal Stability — High heat resistance ensures stable resistance over wide temperature ranges.

  4. High Power Dissipation (5W) — Optimized for continuous and pulsed power applications.

  5. Durable Cement Housing — Provides mechanical protection, flame resistance, and long service life.

  6. Available Tolerances & Mounting Options — Multiple tolerance grades and axial/lead styles available on request.

Applications of Non-inductive Resistor

  • Surge suppression and snubber networks (with an external capacitor)

  • Load testing and dummy load circuits

  • Power supplies and inverters

  • Motor drive boards and industrial controllers

  • High-frequency switching environments where low inductance is required

Quick Note — RC Snubber vs. Non-Inductive Cement Resistor

  • RC snubber = a network (resistor + capacitor) used to damp transients across switches (e.g., IGBTs).

  • Non-inductive cement resistor = a standalone resistor with very low inductance and high pulse capability.

  • It can be used as the resistive element in an RC snubber, but by itself it is not a complete snubber network
