2477 THMCOIN CELLCLIP

Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001 and ISO14001 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility in Shenzhen and Dongguan, proudly presents the 2477 THM Coin Cell Clip. This precision-engineered coin cell retainer is specifically designed for 24.5mm diameter lithium button batteries, including CR2477 and DL2477 models. Manufactured from high-grade phosphor bronze (C5191) on our 11 Japanese/Taiwanese high-speed stamping presses, the 2477 THM Clip features a robust dual-arm retainer design that securely holds the battery in place while providing a reliable, low-resistance electrical path. Key characteristics include stable mounting legs for exceptional PCB retention during wave soldering, tin‑nickel plated contacts for corrosion resistance, support for operating temperatures from -25°C to +85°C, and compatibility with CR2477 batteries rated up to 950mAh capacity. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection performed on every batch.

 

Application Scope: The 2477 THM Coin Cell Clip is ideal for memory backup and standby power applications where long-life, high-capacity coin cells are required. Typical end products include computer motherboards (RTC/CMOS backup), industrial control systems, PLC modules, smart electricity meters, security alarm panels, medical devices (patient monitors, infusion pumps), telecommunication equipment, POS terminals, IoT gateways, and automotive electronics – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the PC pin terminations through the PCB using standard wave or reflow soldering processes. The THM clip mounts securely, and the dual metal arms allow quick, tool-free battery replacement without soldering directly to the battery. Precautions: Do not exceed 3V rating; ensure correct polarity as marked on the retainer; operate within -25°C to +85°C range. Advantages Over Competitors: Unlike competitors who use inferior steel clips with inconsistent spring tension, Antenk’s 2477 Clip is stamped from premium phosphor bronze with a tin‑nickel plating that ensures a consistent and reliable connection over thousands of insertion cycles. Competitors often require 10,000+ MOQ for CR2477 tooling; Antenk offers low MOQs (1,000 units) with no tooling fees for standard configurations. Our IATF16949 certification ensures automotive-grade quality management – most coin cell clip suppliers lack this. Additionally, our 48-hour salt spray testing and 10,000-cycle mechanical insertion validation guarantee superior reliability for demanding industrial and medical applications.

 

Antenk’s vertical integration delivers consistent quality for the 2477 THM Coin Cell Clip. Process flow: (1) In-house mold design and fabrication using our 180+ precision terminal molds (dedicated 24.5mm coin cell progressive tooling); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) using 0.20mm–0.30mm phosphor bronze strip; (3) Barrel plating (tin‑nickel) with real-time thickness monitoring; (4) 100% AOI dimensional inspection with critical tolerance of ±0.05mm on retainer arm spacing and contact height; (5) Spring force testing per EIA-364-04 (45g–65g optimal retention force); (6) Contact resistance testing per EIA-364-06 (below 50 milliohms after insertion); (7) 48-hour salt spray corrosion testing; (8) Automated assembly on 180+ machines with battery insertion force verification; (9) Final QC with lot traceability and full dimensional report. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, and environmental chambers.
