Walsin Microwave Narrow Tolerance MLCCs (UF series) Technical Summary

Graphic with Walsin UF series mlcc on it; read more and procure components today at Sourcengine.

Walsin offers a complete portfolio of MLCCs to fulfill diversified applications from smartphones, networking devices, automotive electronics, to medical.

MLCC consists of a conducting material and electrodes. To manufacture a chip-type SMT and achieve miniaturization, high density and high efficiency, ceramic condensers are used. WTC UF series MLCC is used at high frequencies generally have a small temperature coefficient of capacitance,typical within the ±30ppm/°C required for NP0 (C0G) classification, ultra-narrow tolerance of capacitance and have excellent conductivity internal electrode. Thus, WTC UF series MLCC will be with the feature of low ESR and high Q characteristics.


  1. High Q and low ESR performance at high frequency
  2. Ultra low capacitance to 0.05pF
  3. Can offer ultra-narrow tolerance to ±0.02pF
  4. Quality improvement of telephone calls for low power loss and better performance


  1. Telecommunication products & equipment: Mobile phone, WLAN, Base station
  2. RF module: Power amplifier, VCO
  3. Tuners

** Measured at the conditions of 25 degrees C ambient temperature and 30~70% related humidity.


The lead-free termination MLCCs are not only to be used on SMT against lead-free solder paste, but also suitable against lead-containing solder paste. If the optimized solder joint is requested, increasing soldering time, temperature and concentration of N2 within oven are recommended.
