EPCOS Varistors (S10K275) 275v

The EPCOS Varistor model S10K275 is a leaded surge protection device rated for a maximum operating voltage of 275 volts AC. It has a typical capacitance of 195 picofarads and is designed to absorb up to 43 joules of energy per surge event. The device handles peak surge currents of 2500 amperes under standardized 8/20 microsecond waveforms, as specified in the manufacturer's datasheet. This model is part of the standard energy series, not a high-energy variant, and is suited for moderate transient suppression tasks.

The varistor is constructed using zinc oxide-based ceramic material with a nonlinear voltage-current characteristic, typical of metal oxide varistors. The leaded package allows for through-hole mounting on printed circuit boards. While the supplier does not confirm the exact tolerance on clamping voltage, industry standards for this series typically allow ±10% variation from nominal values. The component is designed for industrial and consumer electronics applications where protection against voltage spikes from switching or lightning-induced transients is required.

This varistor is commonly used in power supplies, telecommunications equipment, and home appliances that require basic surge protection. Buyers in the electronics manufacturing sector source this part for integration into control boards and AC input stages. Packaging is bulk or tape-and-reel, though the supplier does not specify minimum order quantities. Lead times are not confirmed and should be verified directly. Trade terms such as FOB Shenzhen or EXW are typical for this category but must be confirmed with the supplier.

Shenzhen Xhwd Electronics Co., Ltd. is based in Baoan District, Shenzhen, Guangdong, China. The company is listed as a harbor-tier supplier with no verified response rate or average response time recorded. The listing does not indicate factory size, years in operation, or certifications such as ISO 9001. The supplier appears to function as a distributor or trader of electronic components, sourcing products from established manufacturers like EPCOS and offering them under their own business name.

There is no public information confirming production capabilities, quality control processes, or direct manufacturing of the varistors. The supplier does not claim to be an original equipment manufacturer for this part. Buyers should treat this as a sourcing intermediary and verify component authenticity and batch traceability before placing orders. No client references, export history, or third-party audits are disclosed in the listing.
