103M 3kV Ceramic Capacitor Buying Guide

The phrase '103m 3kv' refers to a high-voltage ceramic disc capacitor with a capacitance of 10nF (10,000 pF) and a rated voltage of 3000V DC. The 'M' indicates a tolerance of ±20%. These components are widely used in high-voltage stress environments such as X-ray machines, LED power supplies, and industrial HVDC infrastructure Jeccapacitor Mouser.

Technical Insights

Decoding Logic: The code '103' is shorthand for 10 followed by three zeros (10,000) in picofarads, which equals 10nF Instagram Hv-Caps.
Applications: Beyond consumer electronics, they serve as critical safety components in medical imaging (MRI/CT), semiconductor inspection, and new energy vehicle (NEV) charging systems Mouser Eepower.
Material Trends: There is a shift toward N4700 dielectric materials for better pulse endurance and high stability compared to standard Y5P or Z5U ceramics Hv-Caps.

Market Trends & Sourcing

Pricing & MOQ: Bulk pricing ranges from $0.05 to $0.07 per piece for large industrial orders (MOQ 2,000+), while smaller assortments or lots for testing (e.g., 20-piece packs) retail between $5 and $8 Alibaba Alibaba.
Supplier Clusters: The market is heavily concentrated in Shenzhen and Guangdong, China, where manufacturers offer "drop-in" replacements for legacy brands like Murata and TDK to optimize supply chain costs Hv-Caps.
Compliance: Current market demand is strictly driven by RoHS/Halogen-free compliance and UL94V-0 flame-resistant epoxy coatings, which have become industry standards for high-voltage parts Mouser Hv-Caps.
