How do you verify a MOSFET is truly “logic-level” at 5 V? Not every MOSFET labeled “logic-level” behaves as such when you actually drive it at 5 V. In the lab, you’ll often find devices that promise low Rds(on) on paper but require 8–10 V to reach it. For a real 5 V gate, the only way to be sure is to check the datasheet’s test conditions, not the marketing note.
Which IEC 61000-4-2 level should you target? If you design automotive electronics—especially CAN or CAN-FD interfaces—you can’t escape IEC 61000-4-2. It’s the global ESD standard defining how devices must survive electrostatic discharges in real-world handling. But here’s the catch: not every design needs the top rating.
Preface Every engineer who’s spent time around coax test benches knows that the simplest parts often cause the longest head-scratching. You think you’re just joining two BNC cables, but one tiny coupler—barrel, feed-through, or panel-mount—can quietly decide whether your entire signal chain stays clean or starts to echo.
Preface Every engineer who works with oscilloscopes or RF signal sources eventually faces the same small but annoying puzzle—how to split one BNC signal cleanly between two devices without wrecking impedance balance. That’s where the humble BNC T connector quietly shines.
Preface Every engineer who’s spent time on a lab bench knows the quiet frustration of chasing small reflections that ruin clean waveforms. Most of the time, the culprit isn’t the scope, the cable, or the source—it’s the termination. A single mismatched load can turn a textbook-perfect signal into a jittery mess.
Preface Every RF lab eventually runs into the same simple—but surprisingly tricky—problem: how do you connect an SMA-based instrument to a BNC-terminated cable or oscilloscope without signal distortion?
Preface Every engineer has faced it: a panel that’s ready for wiring, yet the connector just won’t seat right. The BNC bulkhead connector seems trivial until a small mismatch in thread length or washer stack throws off grounding or alignment. It’s the kind of detail that separates a clean install from a noisy one.
Should you still design in PESD2CAN,215 or migrate now? When you design a CAN or CAN-FD interface, one small diode quietly decides your compliance margin — the TVS diode. For years, engineers have trusted Nexperia’s PESD2CAN,215, a compact SOT-23 dual-line transient voltage suppressor built specifically for automotive CAN nodes. Yet, like many reliable workhorses, it now carries a note you can’t ignore: “Not Recommended for New Design (NRND).”
Preface Every engineer remembers that one prototype that powered up just fine—until it didn’t. No smoke, no drama, just a flicker of LEDs, a reset that made no sense, or that faint spark at the connector.
Preface A Transient Voltage Suppressor (TVS) diode is the quiet bodyguard that stands between your circuit and every electrical storm. You rarely notice it—until a static discharge, lightning surge, or automotive load dump hits the line. Whether your board runs on 5 V, 12 V, or 24 V rails, the wrong diode can clamp too late or leak too early.
Preface Outdoor RF work never goes perfectly smooth. A cable that’s one inch too short, or a connector that wasn’t fully seated, can send a clean 5 GHz link into a storm of retries. Over the years, many engineers have learned to trust one component above all—the N-type connector. It’s not glamorous, but it holds the link together when wind, heat, and rain push everything else to the edge.
Preface In wireless systems, a few decibels can decide whether your link runs clean or constantly retries. That’s why an SMA extension cable isn’t just a convenience—it’s an RF decision. Each added meter brings insertion loss, impedance shifts, and extra mated pairs that can nudge your VSWR off spec. TEJTE’s precision-machined SMA-KE/KHD bulkhead connectors, rated DC–6 GHz and tested < 0.15 dB insertion loss per pair, are designed to minimize that penalty.
