The ceramic SMD package provides hermetic sealing and mechanical protection. When connected in the feedback path of a CMOS oscillator with 9pF load capacitance, the piezoelectric effect sustains precise oscillation. The 32.768kHz frequency is divided by 2^15 to produce exactly 1Hz for real-time clock applications.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Crystal<\/td><td>One terminal of quartz resonator<\/td><\/tr><tr><td>2<\/td><td>Crystal<\/td><td>Other terminal of quartz resonator<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Real-time clock (RTC) circuits<\/li><li>Microcontroller timing<\/li><li>Wearable devices<\/li><li>IoT timekeeping<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>FC-135 32.768KHZ 9PF<\/td><td>Epson<\/td><td>32.768kHz 3215<\/td><td>9pF<\/td><\/tr><tr><td>ABS07-32.768KHZ-9-T<\/td><td>Abracon<\/td><td>32.768kHz 3215<\/td><td>9pF<\/td><\/tr><tr><td>ST3215SB32768E0HPWBB<\/td><td>Kyocera AVX<\/td><td>32.768kHz 3215<\/td><td>9pF AEC-Q200<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9812","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9812"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9812\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9812"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9812"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9812"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9812"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
