QFN-48-1EP

Package: QFN-48-1EP_7x7mm_P0.5mm_EP5.15x5.15mm Library: Package_DFN_QFN Category: Microcontroller / IC Pads: 49 Pitch: 0.5mm Body Size: 7.0 x 7.0mm Mounting: Surface Mount

Description

The QFN-48-1EP is a high-density 48-pin Quad Flat No-lead package with 0.5mm pitch and a 7 x 7mm body. The leadless design is more compact than the equivalent LQFP-48 while providing superior thermal and electrical performance through the 5.15 x 5.15mm exposed pad. Houses STM32 microcontrollers (STM32G4, STM32L4), ESP32-S3 modules, nRF52 Bluetooth SoCs, and high-performance analog ICs. Increasingly preferred over LQFP-48 in modern designs for its smaller footprint and better high-frequency characteristics.

Usage Notes

  • Designed for reflow soldering (paste stencil recommended)
  • Pad size optimized for 0.5mm pitch components
  • Follow IPC-7351 land pattern guidelines
