Xiamen SET Electronics Co., Ltd.

Thermal-Link & Fusing Resistor (TRXF) is an unique type of Power Resistor, with Over Temp. and Over Current Protections. The Alloy Thermal-Link (ATCO) is built in the core of Fusible Wirewound Resistor (RXF) and in series with RXF.

SETsafe | SETfuse TRXF has the same physical size as ordinary RXF as well as large fault current protection. Besides, TRXF can effectively solve the hidden danger of continuous abnormal heat that ordinary RXF may cause when small fault current happens.

Overview 1-2_TRXF.jpg

RXF

Fusible Wirewound Resistor

A power resistor which is made by winding a resistive element on a ceramic core, and the core is coated by insulation coating. It intends to interrupt a current flow at a predetermined time when the current exceeds a predetermined value. Fusible Wirewound Resistor is disposable fuse elements and is non-recoverable.

— (SETsafe | SETfuse Standards)

ATCO

Alloy Thermal-Link

Alloy Type Thermal-Link, Alloy is the thermal element.

— (GB/T 9816.3)

Rated Resistance

Resistance value for which the resistor has been designed, and which is generally used for denomination of the resistor.

— (IEC 60115-1)

P₀

Actual Power

The Max. power of TRXF can be used within the allowable operating Temp. range.

— (SETsafe | SETfuse Standards)

I_N

Rated Current

未标题-1.jpg

— (SETsafe | SETfuse Standards)

U_N

Rated Voltage

The d.c. or a.c. r.m.s. voltage calculated from the square root of the product of the rated resistance and the rated dissipation.

— (IEC 60115-1)

T_f

Rated Functioning Temp.

The temperature of the Alloy Thermal-Link which causes it to change the state of conductivity with a detection current up to 10 mA as the only load.

— (IEC 60691)

Tolerance: T_f °C (GB/T 9816, EN 60691, K60691).

Tolerance: T_f ± 7 °C (J60691).

Fusing Temp.

The temperature of the Alloy Thermal-Link which causes it to change its state of conductivity is measured with silicone oil bath in which the temperature is increased at the rate of 0.5 °C to 1 °C / minute, with a detection current up to 10 mA as the only load.

TCR

Temp. Coefficient of Resistance

Relative variation of resistance between two given temp. divided by the difference in the temp. producing it.

— (IEC 60115-1)

Cold Resistance Test

1. If product TCR is not less than 350 (10^-6/°C), the measured resistance value shall be corrected as the relative resistance value under 25 °C according to TCR formula.

2. Resistance Measurement (4-terminal test)

Replacement

As TRXF is a non-resettable product, for safety sake, please use the same type of TRXF for replacement.

Usage

1. Do not touch the resistor body or pins directly when power is on, to avoid burn or electric shock.

2. When air pressure is from 80 kPa to 106 kPa, the relative altitude shall be +2000 m to - 500 m.

Storage

1. Please store TRXF with ambient temp. 10 °C ~ 30 °C and relative humidity 30% ~ 75%.

2. Do not store the TRXF at the high temperature, high humidity or corrosive gas environment, avoid influencing the solderability of the pins, please use them up within 1 year after receiving the goods.

Soldering Parameters

Wave Soldering Parameters (For Reference Only)

The Wave Soldering Parameters are for reference only, before TRXF is for practice usage, relative validation is recommended.
