MRI 是極精密的射頻接收器，任何一條未經濾波的纜線穿透屏蔽室，都可能讓診斷影像變成一片雜訊。EMIS MF420-2CF-M 就是為此而生。

KYOCERA AVX FFLK 系列軌道級 DC 濾波電容：受控自癒介電薄膜、10萬小時壽命、最高3800VDC，終於不需在尺寸和可靠性之間抉擇。

車載充電機 98% 效率、GaN/SiC 開關數百 kHz 運作這些奇蹟的幕後英雄是電容。沒有電容的 DC-link 緩衝，快充啥都不是。

Vishay IHLP1212-EZ-1Z 系列：3×3mm 小 footprint、14.3A 飽和電流，鐵粉體遮蔽封裝讓你不必再拿尺寸換性能。

Digital chips have cryptographic IDs. Passive components mostly don’t. As gray market counterfeits proliferate, critical infrastructure is being exposed to supply chain risks it can’t even…

數位晶片有加密 ID，多數被動元件沒有。灰市仿冒品泛濫，關鍵基礎設施正面臨無法衡量的供應鏈風險——而現在，終於有了解方。

750 kilowatts through a cable the size of your arm. Liquid cooling running at the same time as your battery’s internal BMS. The power electronics behind nine-minute EV charging is a thermal and …

A simple SR-latch relaxation oscillator offers a low-cost, linear interface for differential capacitance sensors — with just ±0.1% nonlinearity after a firmware polynomial correction.

Tee-configuration filters often present uncontrolled rising input impedance in the stopband, which can destabilize driving amplifiers. John Dunn explains the mechanism and a filter-pair remedy.

John Dunn 在 EDN 解析 T 型濾波器於止頻帶輸入阻抗失控的問題，以及如何透過濾波器配對架構讓阻抗在止頻段趨近受控的負載值，提升驅動放大器穩定性。
