ESD protection in the workshop

Mat, wrist strap, safe workbench and component storage. The procedure below focuses on decisions you can apply immediately while building or troubleshooting a circuit.

Key rules

• Store sensitive parts in antistatic packaging.
• A wrist strap equalises potential through a safety resistor.
• Avoid synthetic fabrics and very dry air.

Step-by-step procedure

1. Write down required voltage, current, tolerance and operating conditions.
2. Verify connections and datasheets before applying power.
3. Power up with current limiting and measure defined test points.
4. Record actual values and conclusions in the project journal.

Practical example

Assume a circuit runs from 5 V. Rather than choosing a part by appearance, calculate the required value, check power and absolute ratings, then compare the result with a real measurement. This avoids repeating the same fault.

Common mistakes

• Mixing units or prefixes.
• No electrical or thermal margin.
• In-circuit measurement without accounting for parallel paths.

For mains voltage, high current or stored energy, use appropriate procedures and qualified help. LutujTo does not replace manufacturer documentation.
