Y2 film capacitors with an increased rated voltage
TDK Corporation has released its latest series of EPCOS MKP Y2 capacitors for EMI suppression. They offer a permissible rated voltage of 350 V AC.
The capacitances of the B3203 series range from 4.7 nF to 1.2-microF. TDK says that, even under harsh environmental conditions, the capacitors offer a stable capacitance value.
They are certified according to IEC 60384-14:2013/AMD1:2016 and classified in accordance with “Grade III high robustness under high humidity Test B.” This is verified by a temperature, humidity, bias (THB) test at 85 degrees C, 85 per cent relative humidity and 350 V AC operating voltage, at which a capacitance drop of no more than 10 per cent may occur. The maximum operating temperature is 110 degrees C.
The capacitors are approved in accordance with UL and EN and qualified to AEC-Q200. Depending on their capacitance, they are available with a lead spacing of 15mm (B32032), 22.5mm (B32033), 27.5mm (B32034) or 37.5 mm (B32036). The case and the epoxy resin sealing comply with UL94 V-0.
Y2 capacitor applications include EMI suppression in filters that are subjected to harsh environment conditions and demand higher rated voltages, such as those in photovoltaic inverters or in automotive.
TDK’s portfolio features passive components such as ceramic, aluminum electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices.
The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices and magnetic heads.
These products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.
The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
In fiscal 2018, TDK posted total sales of US$12bn and employed about 103,000 people worldwide.
