Varistor
Guangdong Foshan Kestar Electronic Co., Ltd. supplies metal‑oxide varistors (MOV) that protect equipment from transient over‑voltage events. The devices consist of a zinc‑oxide semiconductor matrix embedded in an epoxy resin coating, and are offered in disc form for easy mounting on printed circuit boards. Typical product data include a clamping voltage range from 150 V to 10 kV, energy absorption capacities from 10 J to 500 J and operating voltage ratings that suit industrial and consumer electronics.
In the industry varistors are classified by their voltage‑dependent resistance characteristics; a typical device shows a nonlinear V‑I curve that limits surge voltage within milliseconds. Standard dimensions for disc‑type MOVs range from 10 mm to 50 mm in diameter, with a tolerance of ±0.5 mm, and the epoxy coating provides moisture resistance and mechanical protection. Compliance is usually demonstrated against IEC 61643‑2, which defines performance tests for surge protective devices.
OEMs of power supplies, UPS systems, telecom equipment and motor‑drive units frequently specify these varistors for surge protection. Importers should confirm the required clamping voltage, energy rating and disc size, and arrange for the mill test certificate and IEC compliance documentation. Trade details such as the minimum order quantity, packaging in anti‑static bags and the preferred incoterm (e.g., FOB Shenzhen) need to be clarified with the supplier before placing a purchase order.

Guangdong Foshan Kestar Electronic Co., Ltd. is situated in the industrial zone of Foshan, Guangdong Province, China. The company holds a harbour‑level trust rating, indicating a verified business presence, although its platform response rate is currently recorded as zero percent, so direct contact may be required for detailed enquiries.
Metal Oxide Varistors (MOV) are key components in surge protection and lightning arrester systems, providing voltage-dependent resistance to clamp transient overvoltage events. Widely used in power systems, industrial equipment, and consumer electronics for overcurrent and overvoltage protection. As critical import items for electronics manufacturers and electrical equipment suppliers, MOV components are traded globally in bulk quantities with pricing varying by disc diameter, clamping voltage, and energy absorption capacity.

Sourcing Varistor from Guangdong Foshan Kestar Electronic Co., Ltd. - China Import Guide
Importers should first verify that the varistor meets the required IEC 61643‑2 standard, request the test report and confirm the clamping voltage and energy rating match the design specifications. It is also advisable to check the epoxy coating integrity and ensure the disc dimensions are within the stated tolerance.
Logistics for electronic components typically use FOB terms at the port of Shenzhen, with shipment in sealed anti‑static bags or bulk cartons. Lead‑time estimates usually range from two to four weeks after order confirmation, but the exact schedule must be agreed with the supplier, as well as the payment method such as T/T or LC.
Quality assurance should include a visual inspection for coating defects, measurement of disc diameter, and functional testing of the voltage‑dependent resistance curve. Importers are encouraged to arrange a third‑party inspection or request a sample for laboratory verification before full production, and to retain all certificates for customs clearance and warranty purposes.
