Caution/Notice:
1. Storage and Operating Conditions: Avoid corrosive gases, volatile substances, and extreme environmental conditions to prevent product deterioration.

Storage and Operating Conditions:

Recommended storage temperature is between -10 to +40 degrees Celsius with humidity less than 75% RH to prevent solderability decline.
Products should be used within 6 months of delivery, following a first-in, first-out system.
After unpacking, products should be resealed or stored in a sealed container with a drying agent.
Avoid storing in corrosive gases or direct sunlight.

Handling and Soldering:

Avoid melting solder in the resin head during soldering to prevent wire breakage or short circuits.
Do not touch the resin head directly with a soldering iron.
Do not separate parallel lead wires within 10mm of the resin head.
Evaluate product quality if molding with resin.
Do not bend lead wires with a radius of 1mm or less.

Product Features:

Lead-free ceramic element, suitable for power supplies under 100W.
Excellent recovery characteristics due to resin coating.
Highly reliable for applications like switching power supplies, CRT monitors, and color televisions.

Specifications:

Operating temperature range: -20°C to +160°C.
Various part numbers with specific resistance, permissible current, and thermal characteristics.

Safety and Usage Notices:

Ensure a fail-safe function to prevent secondary damages from product failure.
Use within specified temperature and current limits to avoid deterioration or fire risks.
Designed for use with smoothing capacitors in switching power supplies.

Product Specifications and Usage Conditions:
This product is intended for use in ordinary environments with normal room temperature, humidity, and atmospheric pressure. It should not be used in conditions involving corrosive gases, volatile or flammable gases, dusty environments, high or low pressure, wet or humid conditions, proximity to salt water, oils, chemical liquids, or organic solvents, strong vibrations, or other hazardous conditions.

Handling and Safety Notices:
1. The product may reach temperatures of approximately 160°C during operation. Ensure surrounding materials can withstand such temperatures to prevent deterioration or harmful gas production.
2. The product is not waterproof; exposure to water can cause failure or current leaks.
3. The ceramic element is fragile; avoid excessive force or shock to prevent cracking or chipping.
4. Avoid excessive force on the lead wire to prevent breakage or cracking.

Inrush Current Considerations:
1. The product may allow higher current passage after an inrush current until it cools down and recovers its original resistance.
2. The resin coating does not guarantee insulation; maintain adequate insulating distance from surrounding parts.

Packaging and Dimensions:
The document provides detailed dimensions for various packaging types, including bulk and ammo pack taping, with specifications for component pitch, sprocket hole pitch, lead spacing, and other relevant measurements.

General Notes:
Users are advised to read the ratings and cautions for storage, operation, soldering, mounting, and handling to prevent smoking or burning. The catalog contains typical specifications, and users should consult the product specifications or approval sheet before ordering.
