工程计算器
面向替代器件评审的进阶计算
对寿命、浪涌、降额、隔离和热裕量做一阶计算。这些估算帮助判断哪些替代料需要更深入的数据手册评审、仿真或实验室测试。
Advanced engineering calculators
Lifetime, surge, derating, isolation, and thermal estimates
Inputs accept up to 6 decimal places. Intermediate values are rounded to 8 decimal places, and final results display 7 decimal places.
Capacitor lifetime
Estimate electrolytic capacitor lifetime using the 10C rule.
L_est(h) = L_rated(h) x 2^((T_rated(C) - T_hotspot(C)) / 10)
This is a first-pass estimate. Use the vendor lifetime curve for final approval.
Estimated lifetime
40,000.0000000 h
Temperature exponent = 3.0000000.
