1. INTRODUCTION  
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 RH series MLCC are used at high frequencies generally and have a small temperature coefficient of  
capacitance, typical within the ±30ppm/°C required for X8G classification and have internal electrodes of excellent  
conductivity. Thus, WTC RH series MLCC will have the feature of low ESR and high Q characteristics.  
WTC RH series have high reliability characteristic, life test condition: 150/ 2000hrs / 2xRated Voltage.  
2. FEATURES  
3. APPLICATIONS  
b. High Q and low ESR performance at high frequency.  
c. Ultra low capacitance to 0.1pF.  
d. Ultra high reliability ( 150/ 2000hrs / 2x Rated  
Voltage).  
a. Telecommunication products & equipments: Mobile  
phone, WLAN, Base station, Small cell.  
b. RF module: Power amplifier, VCO.

Storage and handling conditions  
(1) To store products at 5 to 40°C ambient temperature and 20 to 70%. related humidity conditions.  
(2) The product is recommended to be used within one year after shipment. Check solderability in case of shelf life  
extension is needed.  
Cautions:  
a. The corrosive gas reacts on the terminal electrodes of capacitors, and results in the poor solderability.  
Do not store the capacitors in the ambience of corrosive gas (e.g., hydrogen sulfide, sulfur dioxide,  
chlorine, ammonia gas etc.)  
b. In corrosive atmosphere, solderability might be degraded, and silver migration might occur to cause low  
reliability.  
c. Due to the dewing by rapid humidity change, or the photochemical change of the terminal electrode by  
direct sunlight,the solderability and electrical performance may deteriorate. Do not store capacitors under  
direct sunlight or dewing condition. To store products on the shelf and avoid exposure to moisture.  
Recommended soldering conditions  
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.
