KPT-2012SURCK LED Lamps: Essential Guide for Electronic Projects in South Africa

Overview: What is the KPT-2012SURCK LED Lamp?

The KPT-2012SURCK is a surface-mount device (SMD) LED, commonly used as an indicator lamp or status light in a wide range of electronic projects. Its compact 2012 metric package (2.0mm x 1.25mm) makes it popular in modern PCB designs, from microcontroller circuits in education kits to production logic boards.

Many South African makers, students, and technicians choose the KPT-2012SURCK or its equivalents because of reliable brightness, easy footprint compatibility, and availability from local distributors like Communica. The device uses an AlGaInP (aluminium gallium indium phosphide) die for enhanced efficiency, making it suitable for both battery-powered and mains-driven designs.

Specifications and Standards

Below is a quick reference table of key parameters for the KPT-2012SURCK SMD LED. Always confirm details with the latest datasheet or specific batch marking, especially if ensuring cross-compatibility with similar SMD components:

This SMD LED complies with RoHS directives, making it suitable for academic and industrial designs in South Africa.

Common Use Cases in South Africa

• Indicator/status lamps on Arduino, STM32, ESP, Raspberry Pi, and microcontroller boards
• Visual feedback in prototyping circuits and robotics kits
• Signal, error, or power-on display in student or tertiary practicals
• Compact industrial controller panels and sensor interfaces

Selection Criteria and Local Stock Insights

When selecting the KPT-2012SURCK or similar 0805/2012 SMD LEDs for your build, consider these factors:

• Brightness: Match the luminous intensity (mcd) to ambient lab or workshop lighting
• Colour: This model emits super-bright red; choose accordingly for functional clarity
• Circuit Voltage: Forward voltage is around 2V; design your current-limiting resistor using this parameter
• Footprint: Use 2012 (metric) or 0805 (imperial) pads in your PCB design
• Supplier Availability: Communica holds stocks of these and equivalent models from brands like Kingbright, Everlight, and local alternatives suitable for rapid project fulfilment

Lead times are generally short for standard SMD LEDs, but check the branch hours and inventory for project-critical quantities or bulk needs.

Design Calculations: Sizing Series Resistors

To safely operate the KPT-2012SURCK, calculate your series resistor using Ohm's Law. The formula is:

R = (V_Supply - V_F) / I_F

Example: With a 5V supply, KPT-2012SURCK V_F = 2.1V, desired I_F = 15mA:

R = (5V - 2.1V) / 0.015A ~ 193Ohm (choose 200Ohm standard value for reliability)

In SMD layouts, ensure correct polarity (anode/cathode) according to your PCB's silkscreen. The longer pad is the anode (positive).

Troubleshooting Common Issues

• Dim or Non-Illuminating LED: Verify resistor value, polarity, and PCB tracks. Check for solder bridges or cold joints; reflow as necessary.
• LED Overheats or Fails: Series resistor may be too low-measure current draw (should not exceed 20mA).
• Multiple LEDs, Inconsistent Brightness: Ensure each LED has its own resistor for balanced intensity; shared resistors can cause voltage drop variance.
• Difficulty Soldering SMD: Use fine-tipped irons or hot-air stations, common in South African engineering labs and accessible from suppliers like Communica.

Sourcing KPT-2012SURCK LEDs Locally

Communica stocks KPT-2012SURCK LEDs and similar SMD lamps, supporting local collection at Samrand, Pretoria, and Cape Town branches. Account quotations and VAT invoices are available for educational orders or business procurement. Equivalent models (e.g., Kingbright, Everlight) offer drop-in replacements if supply varies.

Browse the All Products or Shop by Brand page to check current stock and variants. Lead times for SMD LEDs are typically short but always verify availability for high-quantity runs.
