Analysis and Application of EGM16FT1R02DES Anti Surge Metal Film Chip Resistance Technology
1、 Product Overview and Core Features
EGM16FT1R02DES is an anti surge metal film surface mount resistor developed by Egnition. It is packaged in 1206 (3.2mm × 1.6mm), with a resistance of 1.02 Ω, an accuracy of ± 1%, a power of 1W, and a temperature coefficient of ± 50ppm. It is designed specifically for high reliability circuits. This product has the following core advantages through special metal film technology and structural optimization:
Excellent surge resistance performance
Surge current is a common instantaneous high-energy impact in circuits, which may cause component damage or system failure. EGM16FT1R02DES has significantly improved its pulse energy absorption capability through optimization of metal film materials and special process treatments (such as increasing the conductive area), which can withstand short-term high current shocks and protect sensitive components at the back end. For example, at the charging port or power input terminal, this resistor can effectively suppress the impact of surges on the circuit.
High precision and stability
Adopting precision manufacturing technology, the resistance accuracy reaches ± 1%, and the temperature coefficient is as low as ± 50ppm, ensuring minimal resistance fluctuation within a wide temperature range of -55 ℃ to+125 ℃. This feature makes it suitable for scenarios that require high parameter consistency, such as precision voltage division and current detection.
Heat dissipation and power design
The 1206 package provides a large heat dissipation area, combined with the high thermal conductivity of the metal film material, allowing the resistor to maintain a low temperature rise at 1W power and extend its service life. Compared to traditional thick film resistors, its heat dissipation efficiency is improved by about 30%.
Environmental compliance
Compliant with RoHS (2011/65/EU) and REACH regulations, free of halogens and harmful substances, meeting global environmental standards.
2、 Technical parameters and selection points
The key parameters of EGM16FT1R02DES are shown in the following table:

3、 Application scenario analysis
Industrial control equipment
EGM16FT1R02DES is commonly used for current detection and surge protection in motor drive circuits in devices such as PLCs and frequency converters. For example, the IGBT module of a frequency converter is susceptible to switch surges. By connecting this resistor in series, transient currents can be limited, and precise control can be achieved through the use of sampling circuits.
Automotive Electronic Systems
Automotive ECU, ABS and other modules have extremely high reliability requirements. This resistor can be used for CAN bus terminal matching or sensor signal conditioning. Its anti vibration and high temperature resistance characteristics (-55 ℃ to+125 ℃) comply with the AEC-Q200 standard and are suitable for harsh environments such as engine compartments.
Consumer electronics products
In fast charging adapters or amplifier circuits, the EGM16FT1R02DES can suppress surge currents during insertion and removal. For example, the USB PD fast charging protocol requires the port to withstand transient shocks of 20V/5A, and this resistor protects the backend IC from damage through a dual mechanism of current limiting and energy absorption.
Medical equipment
Medical equipment such as electrocardiographs require high-precision signal acquisition. The low temperature coefficient and high stability of this resistor can reduce measurement errors, while its anti surge characteristics ensure the safety of the equipment during power grid fluctuations.
4、 Compare the advantages of similar products
Compared with the Tian'er TGL1206 series (such as TGL120610F1R00P05Z), the EGM16FT1R02DES is more competitive in the following aspects:
Resistance range: The Tian'er series covers 1 Ω to 250 Ω, while the Yineng model is optimized for low resistance scenarios near 1 Ω, with higher accuracy;

Cost effectiveness: Yineng products have a price advantage under the same performance, especially suitable for mass applications in consumer electronics.
5、 Future Trends and Innovation Directions
With the popularization of electric vehicles and 5G communication, anti surge resistors need to be developed towards higher power density (such as 2W/1206) and lower temperature coefficient (± 25ppm). In addition, integrated design (such as built-in temperature sensors) will become a trend to support real-time monitoring of smart circuits.
EGM16FT1R02DES has become the preferred component in industrial, automotive, consumer electronics and other fields due to its surge resistance, high precision and reliability. In the future, with the upgrading of circuit protection requirements, this type of resistor will further expand its application boundaries under the promotion of new materials and integrated technologies. Engineers need to comprehensively consider the working environment, cost, and long-term stability when selecting models to achieve system level optimization design.
