V510LA40AP – Littelfuse 820V 4.5kA Varistor Through Hole,P=7.5mm

Littelfuse develops technologies for circuit protection, power control and sensing. Its component portfolio includes conventional and resettable fuses, TVS protection devices, gas-discharge tubes, varistors, power semiconductors, integrated protection and control devices, relays, switches and sensors. These product groups support the protection and control needs of industrial electronics, transportation systems, consumer and commercial equipment, communications and energy applications.

Protection components are highly dependent on the exact electrical and mechanical rating. Working voltage, current rating, interrupting capability, surge behavior, package, agency approval and qualification can vary between nearby part numbers, so a family-level match is not sufficient for purchasing or replacement decisions. The exact Littelfuse manufacturer part number should remain the primary BOM identity.

HKEQGOO organizes Littelfuse electronic components by exact manufacturer part number so customers can review the specific package and documentation required for an RFQ. Brand-level information provides context only; stock, lifecycle, compliance, date code, inspection requirements and engineering substitution suitability should be confirmed for the exact part involved in each quotation.
