Notice for TAIYO YUDEN Products

Reminders:

Product information is current as of October 2010 and may change without notice. Verify specifications before use.
Taiyo Yuden is not liable for defects from conditions outside specified parameters.
Products are for general electronics; consult Taiyo Yuden for critical applications like medical or transportation.
Not suitable for aerospace, nuclear, or military applications.
Validate and verify in actual conditions before shipment.
Taiyo Yuden is not responsible for intellectual property disputes from product use.
Export of certain items may require specific procedures.

Product Specifications:
Features:

High-speed response for ESD protection.
No polarity, effective in both directions.
High resistance to static electricity.
Available in 1005 (0402) and 0603 (0201) case sizes for high-density mounting.

Ordering Codes and Dimensions:

Ordering codes specify type, dimensions, capacitance, varistor voltage, and packaging.
Standard quantities for taping: 10,000 pcs for 1005 type, 15,000 pcs for 0603 type.

Reliability Data:

Operating temperature: -55 to +125°C for VR1005, -40 to +85°C for VR063.
Storage temperature: -55 to +125°C.
Tests include high temperature loading, thermal shock, solderability, and resistance to soldering heat.
Reliability tests ensure no mechanical damage and adherence to electrical characteristics.

Precautions:

Verify operating environment and electrical ratings.
Ensure operating voltage is below rated values.
Design PCB land patterns to minimize mechanical stress and ensure proper soldering.
Plan varistor layout on PCBs to minimize stress during manufacturing processes.

Technical Considerations:

Recommended land dimensions and pattern configurations prevent excessive solder amounts.

Specifications and Design Considerations:

Excess solder affects chip durability against mechanical stresses. Proper land-pattern design is crucial.
Avoid mixed mounting of SMD and leaded components, close placement to chassis, and horizontal component placement.

Varistor Layout and Mechanical Stress:

Position varistors to minimize mechanical stress from board warp or deflection.
Consider PCB splitting procedures; push-back and slit methods are less stressful than V-grooving and perforation.

Precautions for Multilayer Chip Varistors:

Automatic placement requires careful adjustment of mounting machines to avoid excessive impact loads.
Correct adhesive selection and application prevent degraded varistor characteristics.
Soldering requires controlled flux application and adherence to recommended temperature profiles to avoid thermal shock.

Cleaning and Post-Cleaning Processes:

Choose cleaning solutions based on flux type and purpose.
Avoid excessive ultrasonic cleaning to prevent varistor damage.
Resin coatings should not exceed the varistor's operating temperature to prevent damage.

Handling and Storage:

Use appropriate devices to split PC boards and avoid stress.
Avoid subjecting varistors to mechanical shocks.
Maintain low humidity and temperature for storage to preserve solderability and packaging integrity.
