TRFM overview

TRFM is a component documented by Ningbo Tianbo Ganglian. The PDF description identifies it as "Max.switching current 25A." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • Nil: (Standard), R1: Coil parallel with 1/2W resistor 1800 for Coil voltage 6VDC, Coil parallel with 1/2W resistor 6800 for Coil voltage 12VDC, Coil parallel with 1/2W resistor 27000 for Coil voltage 24VDC D1: Coil parallel with diode 1N41.
  • Switching Frequency fechanical: 18,000 operations/hr Electrical: 1,800 operations/hr Humidity 85%(at 40°C) Weight Approx: 189 Safety Standard m Engineering Data Life Expectancy Contact Switching Capacity 1000 = 8 eS 00 z 8 | = = Havoc S200.
  • In case the tolerance is not shown in outline dimension, the tolerance should be 20.2mm for outline dimensions 1mm; 0.3mm for outline dimension: 1~Smm and £0.4mm for outline dimension>Smm, 2), The tolerance without indication is always +0..

Engineering review checklist

  • Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
  • Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
  • Review package thermal resistance, copper area, polarity marking and transient derating before layout release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
