what is MELF resistors?

MELF resistors are able to provide higher levels of performance in terms of long term stability, moisture resistance, reliability, and the resistance to the effects of temperature. it is considered a substitution of SMD resistor These resistors are not nearly as widely used as the standard SMD resistors, but in some instances they provide advantages and can be used.

Introduction of the real professional manufacturer in China

Thunder Precision Resistor Co., Ltd. is 29 years experienced professional manufacturer of high precision resistors, ultra-precision resistor networks, precision MELF resistors, precision wire wound resistors, current shunts and lot of special resistors in China.

SGS test report of packing materials made by Thunder Precision Resistors

Thunder Precision Resistor Co., Ltd. applied RoHS and Reach Test to guarantee all materials used in the products as well as the packing materials meet the Restriction of Hazardous Substances and REACH/SVHC requests. Thunder Precision Resistor Co., Ltd. requested all the material suppliers to provide RoHS and REACH/SVHC test reports annually and applied the RoHS and REACH/SVHC tests our selves occassionally to make sure all materials are under control even the packing materials.

Ultra precision resistor voltage divider is one kind of special designed resistor networks

Ultra precision resistor voltage dividers are one kind of special designed precision resistor arrays. The original Ultra precision resistor voltage dividers are introduced from CADDOCK America in 1990. Thunder Precision Resistor Co., Ltd. designed new kind of TC1776 for replacements of 1766 from CADDOCK and it did replaced all of 1766 after that.

Thunder Precision Resistor Co., Ltd. is one with more than 29 years experienced professional manufacturer

There are so many company advertised they are manufacturers of ultra high precision resistors both in China and in the world. but there are only few of companies in China who can really make ultra-precision resistors. Among them, Thunder Precision Resistor Co., Ltd. is one with more than 29 years experienced professional manufacturer.

The quantity of the tin paste affects the soldering quality of MELF resistors dramatically and obviously!

Melf resistors are cylindrical type SMT resistors. There are only two tangential line of each resistors that contact the caps to the PCB so that the tin paste quantity must be quite more than normal use for chip resistors soldering to make good soldering by getting the tin soldering materials climb up to the caps. The quantity of the tin paste affects the soldering quality dramatically and obviously!

EOS makes these resistors out of tolerance even them can stand 9 times rated power!

The destructive damage was found at the metal oxide film resistors where affected resistors turned out of tolerance in a short periods, sometimes few days late, the resistors recovered after the tension of the stress released. The recovery of the resistors could be accelerated by kneading the resistor body of leads, or by short time overload to trig the tension off. Thunder Precision Resistor Co., Ltd. makes a lot of high power metal oxide film resistors with huge over loading capability
