9.Application Guidelines
9.1 Circuit Design
Specialty Polymer Aluminium Electrolytic Capacitor should be used in compliance with the following guidelines.
9.1.1 Prohibited Circuits for use
9.1.2 Voltage
9.1.3 Ripple Current
9.1.4 Leakage Current
9.1.5 Failure Rate
(1) This specification guarantees the quality and performance of the product as individual components.
(2) Do not use the products beyond the specifications described in this document.
Do not use the capacitor with the following circuit.
(1) Time-constant circuit
(2) Coupling circuits
(3) 2 or more capacitors connected serially
(4) Circuit which are greatly affected by leakage current
The application of over- voltage and reverse voltage described below can cause increases in leakage current
and short circuits.
Applied voltage, refers to the voltage value including the peak value of the transitional Instantaneous voltage
and the peak value of ripple voltage, not just steady line voltage.
Design your circuit so than the peak voltage does not exceed the stipulated voltage.
[Over-voltage]
[Reverse-voltage]
Use the capacitors within the stipulated permitted ripple current.
When excessive ripple current is applied to the capacitor, if causes increases in leakage current and short
circuits due to self-heating.
Even when using the capacitor under the permissible ripple current, reverse voltage may occur if the DC bias
voltage is low.
There is a risk of leakage current characteristics increasing even if the following use environments are within
the stipulated range.
However, even if leakage current increases once, it has the characteristic that leakage current becomes small
in most cases after voltage is applied due to its self-correction mechanism.
(1) After re-flow
(2) Shelf conditions such as (1) high temperature with no load, (2) high temperature high humidity with no load
The majority of failure modes are short circuits or increases in leakage current.
The main factors of failure are mechanical stress, heat stress and electric stress due to re-flow and heat from
the use temperature environment.
Even within the stipulated limits, it is possible to lower the failure rate by reducing use conditions such as
temperature and voltage. Please be sure to have ample margin in your design.
[Expected Failure Rate]
Do not apply over-voltage in excess of the rated voltage.
Do not apply voltage, which exceeds the full rated voltage when the capacitors receive impulse voltage,
instantaneous high voltage, high pulse voltage etc.
Do not apply reverse-voltage
(1) Date based on our reliability tests: 46Fit or less (Based on applied rated voltage at 105°C)
(2) Market failure rate: 0.13Fit or less (Based on c=0, Reliability standard: 60%)
Before use, check and evaluate their compatibility with installed in your products.
and (3) sudden temperature changes.
