Product: JIN Ke JK30 Polymer Resettable Fuses (30V, DIP) — 100 pcs Key benefits Resettable protection: Automatically limits current and resets after fault removal, avoiding one-time fuse replacements and reducing downtime. Wide selection of trip currents: Choose the exact protection level you need from 17 available ratings to match circuit requirements. PCB-friendly DIP package: Through-hole DIP form factor simplifies board mounting and replacement in existing designs. Cost-effective and reliable: Polymer PTC construction provides repeatable overcurrent limiting for many low-voltage DC applications. What it does and why you need it Protects circuits from overcurrent and short-circuit conditions up to 30V DC. Prevents component damage, reduces service calls, and lowers maintenance costs by resetting after an overload clears. Offers precise current protection options so you can avoid nuisance trips while still safeguarding sensitive electronics. Key specifications Brand: JIN Ke Model: JK30 Voltage rating: 30V Package: DIP (through-hole) Material: Polymer (PTC) resettable fuse Quantity: 100 pcs Size: 0 34A Available current ratings: 0.5A, 0.75A, 0.9A, 1.1A, 1.35A, 1.6A, 1.85A, 2A, 2.5A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A Performance and compatibility Designed for low-voltage DC systems (up to 30V). Compatible with a broad range of consumer and industrial electronics that accept DIP components. Multiple current choices make the JK30 series adaptable to different load requirements without changing part geometry or board layout. Typical use scenarios Consumer electronics: Protect power input lines for chargers, adapters, and small appliances against overloads and short circuits. Power supplies and battery systems: Safeguard DC power rails, battery packs, and UPS circuits where 30V or lower operation and resettable protection are required. Industrial and hobby electronics: Provide overcurrent protection for control boards, motor driver inputs on small robotics, and prototype PCBs where through-hole DIP devices are preferred. Why choose JIN Ke JK30 Multiple curated current options in a single DIP form factor make it easy to standardize protection parts across designs. Resettable polymer technology reduces waste and service interruptions compared with single-use fuses. Supplied in a 100-piece pack for inventory efficiency and cost savings on repairs and production runs.
