Chip Resistor
- 20 -
APPLICATION MANUAL
Applications
Chip resistors are designed for general electronic devices such as home appliances, computer,
mobile communications, digital circuit, etc.
If you require our products with high reliability-performing at more than 125C or below -55C- for
medical equipments, aircraft, high speed machines, military usage, and items that can affect
human life or if you need to use in specific conditions (corrosive gas atmosphere), please contact
us beforehand.
Normal Operation temperature ranges(
)asfollows.
- 1608, 2012, 3216(general, precision) : -55 ~+155
- Others (rectangular, array, trimmable) : -55 ~+125
Although resistor body is coated, sharp excessive impact should be avoided to prevent
damages and adverse effects on characteristics(resistor value, open circuited, T.C.R.).
Storage
To maintain proper quality of chip components, the following precautions are required for storage
environment, method and period.
Storage Environment
- Chip components may be deformed, if the temperature of packaged components exceeds
40C.
- Do not store where the soldering properties can be deteriorated by harmful gas such as
sulphurous gas, chlorine gas, etc.
- Bulk packed chip components should be used as soon as the seal is opened, thus
preventing the solderability from deteriorating.
- The remaining unused chips should be put in the original bag and sealed again or store in
a desiccator containing a desiccating agent.
Storage Time Period
- Stored chip components should be used within 12 months after receiving the components.
If 12 months or more have elapsed, please check the solderability before actually using.
Mounting
Please give more attention not to press the chip owing to the nozzle's improper height when it
is mounted on PCB.
(Excessive pressure may cause exterior damage, change in r esistance, circuit open, etc.)
