The exact-model manufacturer specification references a 70000-hour life expectancy at 40°C, 65% relative humidity and a 90% confidence level. This is a laboratory reliability reference, not an unconditional guarantee for every application.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the acoustical noise level?\u003c\/strong\u003e\u003cbr\u003eThe published noise rating is 33 dB(A). SUNON defines the measurement conditions using a free-air fan operating in a semi-anechoic environment with a microphone positioned one meter from the intake. Installed noise may vary with enclosure construction and mounting.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eHow is EE80251B1-000U-G99 electrically connected?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer drawing specifies three UL 1007 24 AWG leads with a length of 300 ±30 mm. Red is positive, black is negative and yellow carries the F-type frequency generator signal. The signal uses an open-collector output with an external pull-up resistor shown in the manufacturer circuit, and the documented maximum collector current is 5 mA. The fan does not provide a dedicated PWM input. SUNON advises against PWM switching of the power or ground lead.\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eWhat should be checked before ordering EE80251B1-000U-G99?\u003c\/strong\u003e\u003cbr\u003eConfirm the complete SUNON part number, 12 VDC supply, 145 mA rated current, 1.7 W power consumption, 3200 RPM speed, 41 CFM airflow, 0.18 inH2O static pressure, precision ball bearings, 80 x 80 x 25 mm dimensions, 71.5 mm mounting-hole spacing, three-wire configuration and FG monitoring interface. Verify connector termination, wire colors, signal pull-up requirements and host-system compatibility. EE80251B1-000U-A99 is a different functional version, EE80251S1-000U-A99 uses sleeve bearings, and EE80252B1 versions require 24 VDC. Do not substitute these models without confirming the mechanical, electrical and monitoring requirements of the equipment.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/main\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SUNON","offers":[{"title":"Default Title","offer_id":67823820472399,"sku":"LL1-SU-EE80251B1000UG99","price":17.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/7569\/2623\/files\/EE80251B1-000U-G99-01.jpg?v=1792572308","url":"https:\/\/yunshuotrade.com\/products\/sunon-ee80251b1-000u-g99-fan","provider":"yunshuotrade","version":"1.0","type":"link"}
