Surge Power Derating Curve
Pulse Protective Resistor - PPR series, the surge performance between single and repetitive surge.
• SINGLE SURGE PERFORMANCE graph is good for NON REPETITIVE applications operating in an ambient temperature of 70°C or less.
For temperatures above 70°C, the graph power must be derated further linearly down to zero at 150 °C. • To determine applicable surge power in continuous-surge applications: 1. Identify allowable duration and peak power Psurge of single surge; 2. Determine ratio of surge duration/surge OFF time in application; 3. Calculate Papplicable backwardly according to Y-axis of SURGE POWER DERATING CURVE.

Enhanced Film Power MELF Resistor-EFP

The Enhanced Film Power MELF Resistor(EFP series) delivers high power in compact packages and features a power rating from 0.5W to 5W, with a resistance range from 0.5 ohm to 10M ohm. It possesses superior reliability and stability due to the MELF package. Its SMD enabled structure is better in heat dissipation than a chip resistor, and it has a stronger mechanical structure to withstand vibration and thermal shock. The Enhanced Film Power MELF Resistor is suitable for applications such as power supply, telecommunication, medical, and lighting.

Metal Oxide Film Fixed Resistor-MO

Metal Oxide Film Fixed Resistor(MO) features a power rating from 0.5W to 7W and a resistance range from 0.1 ohm to 220K ohm. The standard tolerance is set at ±5% only, with a TCR of ±300PPM/℃. When compared with a metal film resistor, MO can support higher power requirements and withstand large pulse loads in high ambient temperatures while maintaining long-term stability. It is flameproof with multi-layer coating equivalent to UL 94 V-0 and is solvent resistant.

Pulse Safety Resistor-MSD

The Pulse safety Resistor(MSD series) features a power rating from 0.25W to 6W, with resistances ranging from 100m ohm to 1M ohm. It is made with the special composite film on a high-grade ceramic substrate, with flameproof multi-layer coating equivalent to UL 94 V-0. The resistor possesses excellent anti-surge capability and can absorb pulses from direct or inductive cross-coupling in the city power line, thereby protecting electric equipment or parts from accidental shock. Furthermore, an attractive point is its low-cost alternative to the wire wound resistor.

Surge Safety Resistor-SSR

The Surge Safety Resistor (SSR series) features a power rating from 0.25W to 5W, with resistance ranging from 10 ohm to 330K ohm. Designed to replace carbon or ceramic composition resistors, the SSR series is a good choice for anti-surge applications such as fuel ignition systems, power charging/discharging circuits, and ECG cables to absorb harmful surge energy, thereby preventing the hazard of fire and circuit damage caused by surge energy with a flameproof coating, it could be an alternative to carbon composition resistors such as KOA/HPC.
