T-1 3/4
T-1 3/4
The T-1 3/4 (Full Name) is a through-hole package designed for general illumination and indicator applications. Featuring small form factor, through-hole design, and high brightness, it delivers compact size and easy installation. Typical dimensions are 5mm diameter and 8mm height with a 2.54mm pin pitch, making it ideal for indicator lights in automotive and consumer electronics. Its radial lead configuration enables direct PCB thermal transfer, while RoHS-compliant materials ensures reliability in industrial environments.

Q:What defines the physical structure of T-1 3/4?
A:Key features include:
- Leadless bottom-mounted pads: Ensures stable PCB attachment.
- Central thermal pad (80% coverage): Enhances heat dissipation.
- 4-pin layout with radial arrangement: Optimizes space efficiency.
- 1.0 mm ultra-thin profile: Ideal for low-profile designs. -
Q:Why choose T-1 3/4 over alternatives?
A:Critical advantages:
- Miniaturization: 30% smaller than SOP-8 packages.
- Thermal Performance: Direct PCB heat path reduces junction temperature by 15%.
- Electrical Benefits: Low-inductance design (<1 nH) for high-frequency stability.
- Reliability: Moisture-resistant substrate (MSL 3 certified). -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 3.2 × 2.5 mm
- Height: 1.0 mm
- Pin Pitch: 0.8 mm
- Material: Copper-alloy leads with Ni/Pd/Au plating
- Temp Range: -40°C to +125°C -
Q:Where is T-1 3/4 typically applied?
A:Dominant use cases:
- Power Converters: Buck/boost ICs (e.g., TI TPS62130).
- RF Modules: Bluetooth/Wi-Fi transceivers (e.g., Nordic nRF52).
- Sensor Interfaces: MEMS sensors (e.g., Bosch BME280). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: 4×4 thermal vias under pad (0.3 mm diameter).
- Solder Paste: Type 4 solder recommended for fine-pitch printing.
- Reflow Profile: Peak temp ≤ 245°C (ramp rate 2°C/sec).
- Inspection: X-ray (AXI) mandatory for void detection.
