{"product_id":"cpceccc21700","title":"21700 Pre-Clamped Empty Cylindrical Cell Case with Built-in PTC and Insulating Gasket, 50 pcs\/pack, CPCECCC21700","description":"\u003cp\u003eAn 21700 cylindrical cell case is a precision-engineered enclosure designed to withstand high internal pressures, provide electrical connectivity, and ensure safety during a failure. The built-in PTC is used to cut off current if the battery overheats. The insulating O-ring is typically made of Nylon or PET, these prevent the positive cap from shorting against the negative side of the steel can. The pre-clamped cylindrical cell case can be used for prototyping show.  \u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 558.8px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCPCECCC21700 (C-PCECCC21700)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.8px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 106.8px;\"\u003e\u003cem\u003eMaterial\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 106.8px;\"\u003e\n\u003cp\u003eCase: Nickel plating carbon steel\u003c\/p\u003e\n\u003cp\u003eCap with PTC, Sealing Gasket: PP; Tab: Al\u003c\/p\u003e\n\u003cp\u003eInsulating gasket: PET\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 279.2px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 279.2px;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 279.2px;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003eCase Dimension (O.D. 21.2mm * I.D. 20.7mm * H 73.1mm)\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCCC21700_case_dimension_160x160.png?v=1766381081\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eCap Dimension (D: 20.4 mm * H: 4.2mm)\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCCC21700_cap_dimension_160x160.png?v=1766381350\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eTop \u0026amp; Insulator: D 14.4mm * H 0.93mm\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 117.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 117.6px;\"\u003e\u003cem\u003eCap and PTC Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 117.6px;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003ePressure limit for current cut-off: 0.8-1.3 MPa\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003ePressure limit for exploration: 1.8-2.4 MPa\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eNo-Action Current: 3.0 A, Action Current: 6.0 A\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003eMax.
