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.
Preface In Wi-Fi, LTE, and IoT systems, a few inches of cable often decide whether the signal is strong or barely usable. That’s where an RP-SMA extension cable becomes quietly essential. It lets you shift the antenna to a clearer spot—away from walls or enclosures—without opening the router or adding adapter stacks that weaken the link.
Preface In 12 V and 24 V power designs, the MOSFET you pick quietly decides more than just current flow—it shapes thermal headroom, reliability, and long-term efficiency. Engineers who’ve burned through prototypes know that Rds(on), Qg, and thermal resistance often matter more than headline voltage ratings.
Preface Inside every compact RF system—from Wi-Fi routers and LoRa gateways to 5G telemetry boxes—clearance is always the first mechanical limit you hit. A straight SMA connector often collides with the case wall or PCB edge long before the cable bends. That’s where a right-angle SMA adapter earns its keep. By turning the port 90 degrees, it lets the coax exit cleanly, reducing strain on both the socket and cable.
Preface Modern LTE and Wi-Fi routers promise “MIMO performance,” yet the hidden variables behind that extra throughput are mostly mechanical—how ports are paired, how antennas are aligned, and how much loss hides inside each coax run. Even a perfect chipset can underperform if one cable path adds 1 dB more loss than the other or if the antennas face different azimuths.
Preface Every outdoor RF system—from a base station on a windy rooftop to a vehicle-mounted telemetry unit—depends on how well its connectors resist moisture, vibration, and corrosion. Even with perfect cables and antennas, a single unsealed joint can destroy your VSWR and flood your equipment. That’s where an IP67 connector comes in.
Should you pick LMR-240 over RG58 cable/RG316 cable for this run? When choosing a 50-ohm coax cable, the decision often narrows down to LMR-240, RG58, or RG316—each with its own trade-offs. For most Wi-Fi, LTE, and RF applications, LMR-240 stands out as the sweet spot between low signal loss, flexibility, and durability.
Should you use an adapter or a short jumper instead? In every RF build — whether you’re linking two Wi-Fi boards or extending a test setup — there’s a moment when you realize: “I just need a few more millimeters.”
