Description

70504-C-50 is a fixed-mount PCB barrier terminal strip from the Molex 38700 series, designed for secure wire-to-board connections in power and control applications. It features a screw clamp with washer structure, ensuring reliable mechanical and electrical contact for medium power levels.

Features

  • Pitch: 8.26 mm (0.325 inch)
  • Screw clamp with washer for strong wire retention
  • Barrier-style design for improved electrical isolation
  • Through-hole PCB mounting
  • High current handling capability
  • Durable thermoplastic housing (black)

Electrical Specifications

  • Current rating: 20 A
  • Voltage rating: 300 V
  • Suitable for medium power distribution and control circuits

Mechanical Characteristics

  • Mounting type: Through-hole PCB
  • Wire termination: Screw clamp with pressure plate (washer)
  • Pitch spacing: 8.26 mm → supports thicker wires and higher creepage distance
  • Component type: One-piece barrier strip

Material Information

  • Housing: High-strength thermoplastic (UL-rated)
  • Contacts: Metal alloy with plating for corrosion resistance
  • Screws: Steel with plating for durability

Functional Description

  • Provides a secure interface between external wires and PCB traces
  • Barrier walls between პოზitions reduce risk of short circuits
  • Screw clamp ensures stable connection under vibration and thermal cycling

Design Notes

  • Ensure proper PCB hole size and pad design for current handling
  • Use appropriate wire gauge to match 20A rating
  • Apply correct torque to screws to avoid संपर्क failure or damage
  • Maintain creepage/clearance distances for 300V operation
  • Consider vibration environment → screw locking may be required

How to Choose This Terminal Block

  • Select based on current (20A) and voltage (300V) requirements
  • Choose pitch according to insulation and wiring needs
  • Barrier type preferred for safety-critical or high-voltage designs
  • Verify compatibility with PCB layout and enclosure constraints

Typical Applications

  • Industrial control panels
  • Power supply distribution boards
  • HVAC systems
  • Machinery and automation equipment
  • Appliances and power electronics interfaces

Alternative / Equivalent Products

  • Molex 387 series (other პოზition counts)
  • Phoenix Contact barrier terminal blocks
  • TE Connectivity Buchanan series
  • WAGO screw terminal strips (alternative connection style)

TT2222 transistor

Description

This is 800V, 10A, NPN Transistor. The TT2222 is a robust NPN transistor engineered by Sanyo (now part of ON Semiconductor), primarily intended for horizontal deflection output in color CRT televisions.

1. Heatsinking is critical—with a 65 W dissipation rating, proper thermal management ensures reliability.

2. Voltage and current margins—the high V<sub>CEO</sub> and I<sub>C</sub> specs provide headroom, but stay within safe operating area (SOA).

Features

• High speed.

• High breakdown voltage

• High reliability (Adoption of HVP process).

• Adoption of MBIT process.

• On-chip damper diode.
