Molex PicoBlade MX1.25mm SMT Header Kit — Assorted Pin Counts
Assorted kit of Molex PicoBlade 1.25mm SMT headers covering multiple pin counts — includes both 53047 SMT vertical (top-entry) and 53048 SMT right-angle (side-entry) headers. All headers mount on the PCB surface via reflow soldering and mate with Molex PicoBlade female housings (51021 series) loaded with 50079-8100 contacts. Rated 1A / 50V AC/DC, ideal for FPV drones, wearables, GPS modules, and compact IoT devices.
Why Choose This Kit?
- ✅ SMT vertical + right-angle headers — both orientations in one kit for maximum PCB layout flexibility
- ✅ Ultra-compact 1.25mm pitch — smallest Molex wire-to-board header, ideal for space-critical PCB designs
- ✅ Reflow solder compatible — no through-hole drilling required, compatible with standard SMT assembly processes
- ✅ Assorted 2–10 pin counts — covers the most common configurations for miniaturized electronics
- ✅ Mates with 51021 + 50079-8100 — standard PicoBlade cable assembly system
- ✅ RoHS2 compliant
