Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001:2015 and ISO14001:2015 certified high-tech enterprise founded in 2007 with over 300 employees and a 10000 square meter Huizhou facility, proudly presents the 1/3 N HORIZONTAL SMT HOLDER. This ultra flat surface mount battery holder is specifically engineered for 1/3 N lithium coin cells measuring 11.6mm diameter by 10.8mm height, also known as CR1/3N or 2L76, commonly used in compact medical and consumer devices. Unlike vertical coin cell holders that add significant height, the horizontal SMT design allows the battery to lie flat on the PCB, achieving an installed height of only 3.2mm above the board. The housing is molded from high temperature LCP Liquid Crystal Polymer rated UL94 V0 with a heat deflection temperature of 280 degrees Celsius, enabling reflow soldering without warpage. The positive contact is a nickel plated phosphor bronze leaf spring with gold plated tip of 0.4 microns, while the negative contact features a dual finger retaining clip. Key characteristics include contact resistance below 30 milliohms, retention force of 70 to 110 grams, continuous current rating of 200mA peak 500mA, an ultra low profile of 3.2mm, and an operating temperature range from -40 to +125 degrees Celsius. The holder includes a polarity key and a tactile battery insertion click. The product is RoHS and REACH compliant and UL recognized under E472792.
The 1/3 N horizontal SMT holder is ideal for ultra thin portable electronics requiring backup or main power from a 3V lithium coin cell, including smart watches, fitness trackers, wireless earbud charging cases, medical patches, glucose meters, digital calipers, remote keyless entry fobs, and IoT sensors – markets where Antenk already serves customers including Flextronics, Foxconn, and Fortune 500 companies across the USA, Germany, South Korea, India, Russia, and beyond. Usage method: the holder is supplied on tape and reel with 1000 pieces per reel for automatic pick and place. Solder the two SMT pads using standard reflow soldering with a peak of 260 degrees Celsius and stencil thickness of 0.12mm. After soldering, slide the 1/3 N battery horizontally into the holder with the positive side facing the marked polarity indicator until the retaining clip snaps into place. The horizontal insertion allows access even in tight enclosures. To remove, use a fine plastic tool to release the retaining clip and slide the battery out. Precautions: do not exceed 200mA continuous current; avoid reflow soldering more than twice; ensure the battery is fully seated before closing the device; operate within -40 to +125 degrees Celsius. Advantages over competitors: unlike competitors who offer only vertical coin cell holders that require 8mm to 10mm of vertical clearance, Antenks horizontal design fits into devices as thin as 4mm total thickness, enabling new product form factors. Competitors often use PBT that warps during reflow; Antenk uses LCP with excellent flatness after soldering. While others require 15000 plus MOQ for horizontal SMT tooling, Antenk offers low MOQs of 1000 units with no tooling fees for standard 1/3 N geometry. Our IATF16949 certification ensures automotive grade reliability, and our in house 40 plus lab test devices including XRF, environmental chambers, and 3D profilers guarantee every batch meets EIA 364 standards.
Antenks vertical integration delivers consistent quality for the 1/3 N horizontal SMT holder. Process flow: first, in house mold design using our 380 plus plastic injection molds with a dedicated horizontal cavity holding a tolerance of plus or minus 0.02mm on battery compartment and pad flatness. Second, injection molding on 10 Japanese Taiwanese 35 to 120 ton machines using LCP resin with melt temperature 330 degrees Celsius, mold temperature 120 degrees Celsius, and cycle time 12 seconds – the material is pre dried to prevent voids. Third, high speed stamping of positive leaf spring and negative retaining clip on 9 Japanese Taiwanese presses using 0.15mm phosphor bronze strip. Fourth, selective gold plating with nickel underplate of 2 microns and gold of 0.4 microns on all contact tips. Fifth, semi automatic assembly including inserting contacts into LCP housing and ultrasonic staking for permanent retention. Sixth, 100 percent coplanarity inspection with all SMT pads within 0.08mm using a laser profilometer. Seventh, spring force testing per EIA 364 04 from 70 to 110 grams. Eighth, contact resistance testing per EIA 364 06 below 30 milliohms. Ninth, reflow simulation test at 260 degrees Celsius for three passes to verify no warpage or solder wicking. Tenth, 48 hour salt spray corrosion testing on sample basis. Finally, tape and reel packaging with 1000 pieces per reel and 100 percent visual and electrical verification. Our laboratory houses more than 40 testing devices including XRF, environmental chambers, and automated spring testers. With over 300 employees, more than 18 mold making machines, and over 180 automatic assembly machines, we provide free samples, complete 2D and 3D CAD drawings with recommended PCB land pattern, and 24 hour technical support. Contact Antenk today for a quotation – we respond within 4 hours and ship 1/3 N horizontal SMT holder samples within 3 days. Ask about volume discounts starting at 5000 units and custom options such as gold thickness, modified retention force, or high temperature LCP.
